| Abstract: | Metabolism of Phenylurea Herbicides. VII. Metabolism Studies and Balance of the Fate of Buturon-14C after Application to Wheat. Radioactivity counts at harvest showed that 89.1% of the label was recoverable. Of this 50.1% was detected in the soil, 12.6% in the straw, 3.7% in the roots and 1.3% in the grain, while 16.2% was converted to radioactive CO2. Only about 50% of the radioactivity in the plant material was extractable. This part of the activity consisted mainly of strongly polar metabolites, while the four less polar buturon metabolites accounted for only up to 12% each. |
